I've got a few more things I'd like to add to Gotcha!, but after that it will be time to work on something else. I've been meaning to try out the fancy new poll feature, so I figured I'd leave it up to the four people who read my blog. ;)
ManoAMano is a complete game as is, though I do need to fix up a few bugs, particularly scoring. I also have a good number of additional classes I'd like to add.
Squadrons is probably the simplest project programmatically, though it is 4.0 enabled so there is a bit of a learning curve with that.
Kingdoms is the oldest of the bunch, and the one I think I'm leaning towards myself. It isn't far from at least playability, though has quite a way to go before I'd consider it complete.
No guarantees I'll actually work on the winner (or any of these projects) next, but I'll at least put it at the top of my list of things I'm ignoring. :P
